Suppose a measuring process developed at NIST determines the mass of an object up to the nearest microgram. The chance error for a single measurement (the epsilon thing) is like drawing a number at random from a theoretical population. Suppose for this problem that the SD of this population is known to equal 6 micrograms. (For a procedure heavily controlled and checked over decades, this would not be an unreasonable assumption. Intro stat books refer to this as "sigma known" situations.) Fill in each blank with the appropriate number.
- The typical error associated with any single measurement using this procedure is about ___ micrograms.
- The typical error associated with the average of 100 independent measurements using this procedure is about ___ micrograms
- Take the average of 100 independent measurements using this procedure to estimate the unknown actual mass of an object.
The margin of error at roughly 95% confidence is about ____ micrograms.
- Take the average of 100 independent measurements using this procedure to estimate the unknown actual mass of an object. The margin of error at roughly 99% confidence is about ____ micrograms. A. 0.06
